Abstract
Background: Cochlear implants also referred to as CIs have emerged as a critical tool to assist candidates with severe to profound SNHL. These devices do not require damaged hair cells in the inner ear’s cochlea to amplify sound anymore but rather they send signals directly to the auditory nerve. Current developments have shifted towards enhancing the rate of speech recognition, voice quality and factors which will facilitate a pleasant usage of the speech to text software.
Objectives: To assess a positive impact of the new version of the cochlear implant in the improvement of speech recognition among the hearing-impaired as well as general hearing quality.
Study design : A cross-sectional study.
Place and duration of study: department of ENT MMC hospital Peshawar from jan 2022 to july 2022
Methods: A cross-sectional study was also carried out on 150 patients with severe to profound hearing impaired. Patients got new models of the cochlear implants and also rehabilitation for the improvement of their hearing. Speech recognition tests and the hearing quality self-assessment was performed at pre-implant and 3 months, as well as 6 months after implantation. SPSS 15 was used to analyze the data and t-tests to compare the results pre and post-implantation with a specific emphasis on the speech recognition accuracy of the patients. The results were analyzed with the help of standard deviation and p-values in order to find out the significance of the data.
Results: 135 of 150 (90 percent) achieved moderate to larger improvement in speech recognition, 5 percent improvement above the baseline (p< 0. 001). For the improvement scores the standard deviation was 8. 2 which shows that the increase observed in participants was generally positive and quite similar. Other self-reported improvements included improvements in sound quality, as well as perceived user satisfaction. In 10% of the patients moderate changes were observed, further 5% patients demonstrated minimal changes, probably owing to their pre-existing predisposition towards auditory changes.
Conclusion: The current developments in the cochlear implants have made an enhanced change to the speech recognition as well as general hearing aid for most of the clients. Such results endorse the further enhancement of CI and its application for fostering the auditory world to patients with significant hearing impairment.
